Re: Erratic Sensor Readings After Ongoing AFR Troubleshooting

One more detail is that SO2 is at 4.08V despite nothing being wired to the SO2 ECU input. This began after the factory wideband stopped being seen in Kpro. Sorry for the typo.

Re: Erratic Sensor Readings After Ongoing AFR Troubleshooting

Yes, the calibration was changed to match the stock 03 Civic Si it was tested on. Immobilizer was turned off. I also tried the low octane tune. It was crank, no start for both, with no fuel pump priming.

It's probably irrelevant, but after receiving the Kpro in 2017 when the car was close to stock ...

Re: Intermittent Afr p1166

I have still not resolved this issue. If there is a suggestion more specific than the problem possibly being related to something in the wiring, that could be really helpful. Please feel free to ask any questions or to request any cooperative action on my part. Thanks.

Re: Intermittent Afr p1166

The ECU was replaced for that reason - not sensing ignition on in a known-good vehicle indicates an ECU problem.

The wiring changes aren't significant, although numerous. It is simply removed components like power windows, wipers, AC, etc. The only component change to the engine harness is the ...

EPS Light - No DTC - No Power Assist - EP3

After removing and reinstalling the dash, the EPS no longer functions. The EPS indicator turns on with ignition and stays on. No DTCs appear using an OBDII scanner or on Kpro.

Clues (?):
- The single-pin brown plug located above the EPS control unit and below / behind the ECU is not connected to ...

Re: k20a3, BC0050 Cams - First Start

The plan is to tune based off the a3 high octane tune, monitor the sensor values, and adjust as needed.

The purpose of this topic is to find someone who has experience with this who knows that X will be helpful/necessary with a setup like this (i.e. stuff to do off the bat).

k20a3, BC0050 Cams - First Start

Hello,

I'm about to start a K20a3 with BC 0050 N/A cams for the first time. The goal is to get it running well enough to drive 50 miles on the highway to get it tuned.

I understand the theory of what will be necessary to get this setup working, how to monitor the sensors, adjust tables, etc ...
